20A MPPT Solar Charge Controller 12V/24V Auto Adaptive

TOPBULL 20A MPPT adopts advanced Maximum Power Point Tracking (MPPT) technology, which captures the maximum power point of the solar panel in real time, ensuring that the batteries are maximized for charging efficiency in all-weather conditions. At the same time, it features a comprehensive electronic protection system, including reverse polarity, battery overcharge/overdischarge, and overload protection, to ensure that your system operates stably in all kinds of extreme weather conditions. In addition, the TOPBULL 20A MPPT is equipped with an intelligent recognition function that automatically recognizes DC system voltages of 12V or 24V and is compatible with a wide range of battery types to meet your diverse energy storage needs.

TOPBULL 20A MPPT solar charge controller is equipped with the revolutionary Power Catcher algorithm, which has a tracking efficiency of 99% and a conversion efficiency of an amazing 98%, ensuring efficient operation 24 hours a day, 7 days a week. Even when there is no load, its energy consumption is extremely low (only 0.4W), dramatically reducing energy loss. Compared to traditional MPPT controllers, it can capture up to 30% more energy, and its power utilization rate is even 10% higher than similar products, bringing unprecedented performance improvement and maximizing power revenue for your solar power system.

The 20A MPPT solar charge controller combines high heat dissipation with durability. The specially designed metal heat sink and dual high-speed smart fans ensure that the device maintains optimal efficiency when charging. At the same time, the application of high-strength corrosion-resistant materials makes this controller work stably in various environments.

This 20A MPPT solar charge controller has a wide range of battery compatibility, supports charging of a wide range of 12V/24V batteries, and is equipped with intelligent MPPT technology to efficiently track the maximum power output of the solar panel. Meanwhile, the device has a built-in temperature compensation function that automatically adjusts the charging parameters to adapt to different temperature environments, ensuring safe battery charging.

This 20A MPPT solar charge controller supports up to 50VDC photovoltaic input voltage and is suitable for both 12V and 24V solar systems, which can carry a maximum input power of 240W and 480W respectively. It is designed to be both rugged for outdoor use and portable, providing users with a stable and reliable solar charging solution.

This solar charge controller is innovatively designed with three modes: lighting control (can be set to switch on and off for 1-24 hours), all-weather automatic shutdown and intelligent mode that automatically adjusts according to the load status to adapt to different needs. It also supports lithium activation to enhance battery performance.

Topbull controllers have successfully passed a number of authoritative certificates including CE, FCC and ROHS to ensure the reliability and safety of the products due to their excellent quality.
